To all whom "it may conccm: 7

Be it known that i, ALEXANDER h'lAILrrro'r,

a citizen of Canada, residing at 'lhorold, in

the Province of Ontario and Dominion oi Canada, have invented new anduseful Improvements in Vehicle vVheels, following is a specification.

My present invention has reference to a vehicle wheel.

My object is to provide the rim of a veincle wheel with means forengaging a tire carrying rim in a manner to easily, quickly andeffectively lock the tire carrying rim on the Wheel rim.

A further object is to provide a wheel with a rim having longitudinallyarranged peripheral grooves and notches between one face of the rim andone end of the grooves, and to produce a the carrying rim having itsinner periphery provided with signed to be first passed through thenotches in the wheel rim and then turned to be received in the groovesin the said rim, means, in the nature of block members being received inthe notches of the tire carrying rim which are also brought intocontacting engagement with the ends of lugs on the tire carrying rim,while locking means is passed through the telly of the wheel and the rimthereon for holding the blocks in such positions and for effectivelysecuring the tire carrying rim on the wheel rim.

still further object is to produce a quick demountable tire carrying rimhaving lugs thereon to be received in grooves in a wheel rim, the saidwheel rim also having notches which communicate with the grooves thereinand provide entrance passages for the lugs on the vehicle wheel, thewheel rim and the telly of the wheel having a slot in alignment with oneof the grooves for the reception of the valve on the pneumatic tirecarried by the tire rim, while blocks are inserted in the said notcheson the wheel rim and locked thereto in an easy but effective manner,said blocks having; their inner ends provided with springs, whereby whenthe locking means is released the said blocks will automatically moveout oi the notches to permit or the easy withdrawal thereof and theseparation of the tire carrying rim from the wheel by the turning of thesaid rim on the wheel to bring the lugs thereof opposite the notches ofthe wheel rim.

The foregoing, and other obiects which will appear as the nature of theinvention is of: which the lugs de- 1 better understood, may beaccomplished by a construction, combination and operative association ofparts, such as is disclosed by the drawings which accompany and whichform part of this specification.

in the drawings Figure l is a side elevation of the improvement.

Figure 2 is a similar view but showing the the carrying rim turned onthe wheel to bring the lugs thereof in alignment with the notches on thewheel rim to permitof the removal or the arrangement of the tirecarrying rim on the wheel rim.

Figure 3 is a sectional view on the line 33 of Figure l and on anenlarged scale.

Figure at is a sectional view on the line 4- 4: of Figure l, also on anenlarged scale. Figure 5 is a fragmentary perspective view of a portionof the tire carrying rim.

Figure 6 is a perspective View of a portion ofthe wheel and the rimthereon.

Referring now to the drawings in detail, the numeral 1 designates awheel for automobiles, the same being of the usual construction, havingspokes radiating from the hub thereof and connected to the telly 2. Onthe telly 2 there is secured in any desired manner or if desired, theremay be formed on the telly of the wheel a rim 3. The rim is of a widthequalling that of the telly and is provided with a plurality ofcentrally arranged spaced peripheral grooves i, From one side of thewheel rim, and in a line with one of the end walls of the grooves 4there are notches 5. if desired, the walls of the grooves l extendingfrom the inner wall provided by the notches 5 may be divided or one ofthe walls may be inclined toward the other wall.

The tire carrying rim is also of the usual construction, and isindicated by the numeral 6 The rim 6 has on its inner face centrallyarranged spaced lugs 7. Preferably these lugs are wedge-shaped and thelugs are of a length to be snugly received in the notches 5 of the wheelrim and the tire carrying rim thereafter turned on the wheel rim tobring the wedge-shaped lugs in the wedge-shaped grooves. The lugs arepreferably of a length equalling the distance between the inner walls oithe notches 5 and the ends of the grooves so that one end of the groovewill be in alignment with the inner wall 05 each notch. in certain ofthe notches, l insert blocks 8. Each block has a rounded opening 9therethrough and has its inner wall provided with a socket 10 in whichis inserted a helical spring 11. The springs 11, pressing against theinner walls of the grooves will have a tendency to force the blocks outof the grooves and out of the notches. The blocks, when arranged in thenotches and in the grooves will be in contacting engagement with one ofthe ends of the lugs on the tire carrying rim, and the wheel rim as wellas the telly of the wheel are provided with openings 12 which align withthe openings in the blocks, and passing through the last mentionedopenings are the stems 13 of headed members 14 which, when received inthe openings in the blocks will hold the same in the pockets providedtherefor.

The openings in the blocks are preferably threaded, in which instance itis not neces sary that the openings in the telly and in the tirecarrying rim be also threaded.

One of the lugs on the tire carrying rim is provided with an openingthrough which passes the valve stem 15 of the pneumatic tire 16, Thewheel rim has an elongated slot 17 which extends from the bolt openingtherein to receive therein the valve stem when the tire carrying rim isturned on the wheel rim. The bolt opening, in this instance may beflared :t'ro1n the outer to the inner surface of the wheel rim and tellyso that by slightly canting the tire carrying rim the valve stem can bereadily inserted through the said opening and thereafter brought intocontact with theend wall provided by the elongated opening when the tirecarrying rim is turned on the wheel.

It is thought that the foregoing description, when taken in connectionwith the drawings will fully set forth the construe tion, operation andadvantages of the improvement and that further detailed description willnot be required. It is, however, thought necessary to state. that thenature ofthe invention is such as to render the same susceptible tochanges in size, proportion, material and other details of construction,and that all such changes as fall within the scope of what I claim maybe resorted to.

Havingdescribeo the invention, I claim In a device as herein set forth,a wheel having a rim provided with spaced peripheral grooves and havingnotches from one of the sidesthereoi' entering the grooves and one ofthe walls of each notch being in a line with one of the end walls ofeach groove, and a tire carrying rim having lugs designed to be passedthrough the notches and turned on the wheel rim to be received inthegrooves thereof, blocks in the notches in contacting engagement with oneend of the lugs, and means for securing the blocks in such posi tion,spring means carried by the blocks contactingthe inner walls of thegrooves for partly projecting the blocks through the notches, and meansfor locking the blocks when fully received in the notches.

In testimony whereof I afix my signature.

ALEXANDER MAILHIOT.
